Validate Javadoc snippets; fix playground bindings; improve CN1 access registry generation and smoke-test verification

[liannacasper]

Motivation

• Validate extracted Javadoc snippets before generating docs and avoid hangs by bounding validation with a timeout.
• Make the playground interpreter resolve common UI bindings reliably (allowing implicit Component usage) instead of using fragile resolver methods.
• Make generation of the CN1 access registry deterministic and verifiable by supporting a local-sources mode and adding runtime checks to the smoke-test harness.

Description

• Add a run_with_timeout helper and pre-JavaDoc validation step that runs validate-extracted-javadoc-snippets.sh with a 300s timeout in .github/scripts/build_javadocs.sh.
• Bind Display and UIManager directly via Display.getInstance()/UIManager.getInstance() and add an explicit Component binding and import in PlaygroundRunner.java, removing the prior resolver methods.
• Replace CSS-related smoke checks with a new smokeComponentTypeResolvesWithoutExplicitImport() test in PlaygroundSmokeHarness that verifies implicit Component resolution works.
• Document new behavior and environment knob in scripts/cn1playground/tools/README.md, including CN1_ACCESS_USE_LOCAL_SOURCES to control whether to scan local sources or release source jars.
• Enhance generate-cn1-access-registry.sh to support CN1_ACCESS_USE_LOCAL_SOURCES=true, robustly download/extract release source jars when used, and present clearer errors.
• Update run-playground-smoke-tests.sh to use bash, regenerate the CN1 access registry from release sources before testing, and assert the generated GeneratedCN1Access.java contains expected com.codename1.ui.* classes (including Component) and omits internal sentinel classes before running the smoke harness.

Testing

• Executed the updated smoke-test driver via scripts/cn1playground/tools/run-playground-smoke-tests.sh, which regenerates the CN1 access registry and runs the PlaygroundSmokeHarness via Maven exec, and the smoke harness checks passed.
• The registry-generation path was exercised for release-source mode and its presence/absence assertions on GeneratedCN1Access.java succeeded.
